“…Majority of researches focused on seeking electron donors to reduce Cu(II) to Cu(I) for the acceleration of the Cu(II)/Cu(I) cycle, such as adding UV/visible light irradiation, harnessing the synergistic effect of metal ions, ,− introducing reagents to promote the circulation of copper species , or the electrophilic properties of pollutants . However, the active components of the majority of catalysts composed of metal ions still suffer heavy metal leaching during catalysis reactions, which run counter to the original intention for heterogeneous catalyst preparation, limiting large-scale application.…”

Heterogeneous catalysis can be enhanced through the construction of effective atom connection for rapid electron transport on the catalyst surface. Hence, this study proposed a new strategy for electron transfer regulation to facilitate redox cycle of Cu(II)/Cu(I). The objective was achieved by successful construction of copper-containing covalent bond through the in situ growth of porous g-C 3 N 4 with oxygen dopants and nitrogen defects (O-CN D ) on CuAl x O y substrate (CuAl@O-CN D ). On the basis of X-ray absorption fine structure (XAFS) and other characterization results, the facilitated redox behavior of copper species by electron transfer regulation was ascribed to the formation of a C−O−Cu bond on the porous-rich superficial of the catalyst; these covalent C−O−Cu bonds shortened the migration distance of electrons between Cu(II) and Cu(I) via Cu(I)−O−C−O−Cu(II) bridge. The construction of copper-containing covalent bonds in the catalyst resulted in efficient PMS activation for a rapid redox cycle of Cu(II)/Cu(I), triggering a series of reactions involving the continuous production of three highly active species (SO 4 •− , • OH and 1 O 2 ). The rapid diffusion and transportation of the generated active species from porous structures directly attack typical pharmaceutically active compounds (PhACs), achieving superior catalytic performance. This study provides a new routine to construct a C−O−Cu bond for PMS activation by regulating the electron transfer to accelerate the redox behavior of copper species for environmental remediation.

“…The catalysts would absorb microwave radiation during the activation process and then generate abundant hot spots, thus accelerating electron movement. 169 Light-assisted activation ( λ = 200–400 nm) was also a promising method for enhancing carbon-activated PS systems. It was revealed that the contaminant degradation was effectively enhanced in a light-assisted PS system.…”
